Maybe it is a bug, maybe it's a feature. For sure later or rather sooner they will steal everything.
I am impressed someone with an account at gpwa since 2012 still promotes them and that they actually pay you. They stole me a lot of expekt players (expekt was a big EU brand when everyone laughed at bet365) and lot from betclic.
I am sorry that I can not answer precisely to your question since they closed whole my accounts, so there is a chance it is still a bug.
